More than 500 military members from nine nations are participating in the annual U.S. Joint Chiefs of Staff-sponsored exercise May 28 - June 8. The goals of the exercise are to strengthen interoperability, facilitate training in crisis response and disaster management, and validate the readiness of deployable military medical and humanitarian assistance teams. The exercise, in the spirit of partnership for peace, directly supports U.S. European Command's theater cooperation efforts and strategy for active security with European countries.
